Below is a link to an excellent blog post which discusses emotions as mentioned primarily in Proverbs,
Wisdom and the Proverbs, part III
Chad (the writer of the blog piece) makes a good point about our emotions, in that some that we may call 'negative' are not always unwanted, such as fear when confronted by some danger.
However, if you're still anxious or fearful long after the danger has passed, it would be a good time to use EFT. So take a look, it's a good message.
